Introduction
After years of diplomatic arm-wrestling and mounting security concerns, Keir Starmer’s government has given China’s “mega embassy” the green light. Communities Secretary Steve Reed approved the controversial diplomatic hub near the City on Tuesday morning, ending months of delays and sparking immediate backlash from opposition parties, security hawks, and local residents. The decision—made after the planning application was “called in”—has reignited debates about national security, underground cables, and whether the UK is selling out for trade deals.
What’s the Big Deal About This Embassy?
Location, Location, Location
The Royal Mint Court site isn’t just any patch of London real estate. It sits near the City of London, right above fibre cables connecting the Square Mile to Canary Wharf. Former security officials have raised eyebrows about China potentially accessing sensitive data flowing through these underground lines. Academics warned that Beijing could tap into energy cables and intercept information passing through nearby infrastructure.
But Ciaran Martin, former head of GCHQ’s National Cyber Security Centre, pushed back hard. Writing in The Times, he called concerns about this specific cable network “simplistic,” noting that sensitive infrastructure runs throughout London. Planning documents also stated there’s “no suggestion” China could actually access or interfere with the cables—intelligence agencies never flagged underground infrastructure as a red flag during the application process.
Security Services Say It’s Fine (Sort Of)
MI5 boss Sir Ken McCallum and the GCHQ director sent a letter to the home and foreign secretaries on Tuesday. Their take? You can’t eliminate every single risk, and trying to do so would be “irrational.” They backed the decision, calling the security mitigations “expert, professional and proportionate.”
The government spokesperson doubled down: “National security is our first duty. Intelligence agencies have been involved throughout the process and an extensive range of measures have been developed to manage any risks.” Translation: trust us, we’ve got this covered.
Security officials reckon consolidating various Chinese diplomatic buildings into one site actually makes things easier to monitor. Some additional security measures could still be added before Chinese officials move in.
Who’s Fuming About This Decision?
Cross-Party Opposition
This approval has united strange bedfellows. Reform UK, the Liberal Democrats, and the Conservatives all oppose it. Even the White House has expressed concerns. James Cleverly, the shadow communities secretary, didn’t mince words: “This is a disgraceful act of cowardice from a Labour Government and Prime Minister utterly devoid of backbone.”
The Lib Dems’ Calum Miller warned that the decision “will amplify China’s surveillance efforts here in the UK and endanger the security of our data.” Tory MPs Alicia Kearns and Tom Tugendhat—two of the loudest critics—argued last year that blocking the embassy was “an opportunity to do what’s necessary to protect this country.”
Local Residents Ready to Fight
Local campaigners aren’t backing down quietly. They’re preparing legal challenges, with planning guru Lord Banner KC expected to lead the charge through judicial review. Protestors have highlighted threats to Uyghurs, Tibetans, Hong Kongers, and Chinese dissidents who’ve found asylum in the UK.
The City of London Corporation told City AM they were “nervous about the threat” from China. Residents worry about more Chinese diplomats and potential spies operating so close to Britain’s financial heart.
Labour MPs Break Ranks
It’s not just the opposition kicking off. Labour MP Sarah Champion, who chairs the Commons international development committee, also opposed the approval. This internal dissent shows just how divisive the decision is, even within Starmer’s own party.
The China Critic’s Take
Luke de Pulford, director of the Inter-Parliamentary Alliance on China, summed up the fury: “This is the wrong decision for the UK, sending all the wrong signals. Wrong for dissidents, wrong for UK national security. Our three Cs China policy is less compete, challenge and cooperate, more cover-up, cave in, and cash out.”
His criticism reflects broader concerns that the UK is prioritising economic ties over security. The timing is especially awkward—the approval comes ahead of Starmer’s expected trip to Beijing, where he’ll bring UK business leaders to boost trade ties.
What Happens Next?
The government insists this is standard diplomatic practice. A spokesperson noted that the process began in 2018 when the then foreign secretary provided formal diplomatic consent. “Countries establishing embassies in other countries’ capitals is a normal part of international relations,” they said.
But normalcy doesn’t mean smooth sailing. Legal challenges could delay or derail the project entirely. Media reports have already uncovered intelligence officials’ concerns and unearthed redacted portions of designs submitted to Tower Hamlets council.
The security protections rely on China’s “lawful embassy use of the site”—a phrase that’ll do little to reassure critics who remember last year’s collapsed Chinese spy case involving Christopher Cash and Christopher Berry (both deny all spying allegations).
The Bottom Line
Starmer’s government has made a calculated bet: consolidating Chinese diplomatic operations into one monitored site outweighs the risks of potential espionage. Intelligence agencies back the decision, security mitigations are in place, and the planning process stretches back to 2018.
But politically, this is messy. Cross-party opposition, angry residents, and internal Labour dissent suggest the controversy won’t disappear. As legal challenges mount and Starmer prepares for his Beijing trip, one question lingers: did the UK just make a smart security move, or trade national safety for trade deals?
